ATI Mobility Radeon HD 545v
The AMD ATI Mobility Radeon HD 545v is a laptop graphics card based on the old Mobility Radeon HD 4500 series. Therefore, the GPU only features 80 shader cores (5-dimensional), DirectX 10.1 support and ist still manufactured in 55nm. The clock rates are identical to the ATI Mobility Radeon HD 5145, which was also presented in 2010. Therefore, both cards are based on the Mobility Radeon HD 4570 (same DeviceId of 9553) with a slightly higher core clock.
It is probably right when it identifies the card as 4500/5100 series. I would leave it alone. No update is going to affect that card's performance.
